Answer 2

It seems like you have a system of linear equations with two variables, $x$ and $y$:

Equation 1: $3x + 4y = 718$ Equation 2: $x - 4y = 182$

To solve for $x$ and $y$, you can use various methods such as substitution, elimination, or matrix methods. I'll demonstrate the elimination method here:

First, let's add the two equations together to eliminate the $y$ terms:

$$\begin{align*} (3x + 4y) + (x - 4y) &= 718 + 182 \\ 4x &= 900 \\ x &= \frac{900}{4} \\ x &= 225 \end{align*}$$

Now that we have the value of $x$, we can substitute it into one of the original equations to solve for $y$. Let's use Equation 2:

$$\begin{align*} x - 4y &= 182 \\ 225 - 4y &= 182 \\ -4y &= 182 - 225 \\ -4y &= -43 \\ y &= \frac{-43}{-4} \\ y &= \frac{43}{4} \end{align*}$$

So, the solution to the system of equations is $x = 225$ and $y = \frac{43}{4}$.
